I've noticed that on desktop, using my lemmy.world account led to me either getting signed out on certain instances or just not being able to interact with them; on Kbin however, the fact that I can see and interact with this post and ones on --for example-- lemmy.blahaj.zone is a good sign. I'll still keep both accounts esp since Jerboa doesn't allow kbin accounts on there, so I'll keep experimenting with this
